I think you read it wrong, Jooin isn't talking about how he wants to end it, he's saying how if things do end he wouldn't like how it will end, that what Cain gives him is something he doesn't want to to come to an end. He was scared so he tried to wedge distance. He confirm he was pushing Cain away to avoid choosing and wanted Cain to be the one push him away instead
he rejected yahwi basically all season, they showed us how much better cain is for him, JUST to end up choosing the bad guy?
make it make sense
